Little Hawk is right about the inclination to make political decisions based upon personalities as being implicit.

People invariably explain their positions in rational terms, but that's not necessarily how they arrive at said decisions.

For every one of us, our choice of candidate is based upon a combination of factors, including stated positions on issues and our confidence that the person in question is capable of, and truly intent upon, acting upon those positions. Our perceptions of personality factors has everything to do with how seriously we take a candidate's ability and honesty. The talk about issues is worth nothing if the person can't or won't stand behind his/her positions.

Also, of course, among individual citizens, the relative weight given to rational vs emotional factors varies quite widely. And when I observe large numbers of voters being so easily swayed by the most specious political commercials, I have serious doubts that many individuals among the electorate are giving serious thought to this deal.
